Description
Technical field
The present invention relates generally to radio communication, more specifically, relates to through using the audio accessory of telework with the wireless connections of mobile communications device.
Background technology
Mobile communications device is widely used in the whole world, especially at the metropolitan area in the world.In recent years, the expense of these devices and communication service reduces greatly, and it is equally matched almost to communicate by letter with landline telephone.For keeping competitiveness, manufacturers have begun to add function its product is different from the product of other manufacturers to the mobile communications device product of oneself.
One has been proved to be very popular characteristics promptly is the scheduling method that a so-called key is logical or communicate by letter.Replenish as what the traditional mobile phone that is called as interconnect call was served, these devices and system support dispatch call.Dispatch call is a kind of half-duplex call, similar and two-way radio or walkie-talkie operation.In addition, dispatch call is controlled by the logical operation of a key, wherein, and for example when the user presses ptt button and loquiturs.Therefore this scheduling method needs a kind of low call setup stand-by period so that as much as possible near instant.At the receiving system place; In case receive the calling dispatch call, be different from interconnect call, receiving system is when responding to the incoming call paging from communication system; Just promptly activate loud speaker and begin to play the audio-frequency information that receives, and do not need any action of the user side of receiving system.
For mobile communications device, there are various annexes to use, it is a kind of that to be proved very popular particular type recently promptly be wireless headset.Wireless headset is worn on user's the ear, and through local wireless link, for example well-known bluetooth and being connected with mobile communications device.Because these annexes and mobile communications device are wirelessly operated, so they must have their power supply, but need be worn on user's the ear because of them, and they also must be very little, so big battery can not adopt.Therefore, need operation earphone under low-power mode as much as possible.A kind of method that can realize power save operation make earphone get into " sleep " pattern exactly and periodically detect with watch mobile communications device whether its transmission of forward anything.This operating in worked in the interconnect call well, because in interconnect call, before receiving any audio-frequency information, the user of receiving system must at first answer the call, and this removes to wake up earphone to state of activation just for the mobile communications device time.But in dispatch call, the stand-by period of waking up in the earphone process just becomes very crucial.If mobile communications device response calling dispatch call, and before earphone is waken up, just set up the calling dispatch call, the conversation of then partly being sent may be lost or can not be heard by the user.Therefore, for handling dispatch call, be necessary to reduce and wake earphone the time that spends to state of activation up from low power state.

Embodiment
Although specification is summed up by claim; Said claim has defined the inventive features that is considered to have novelty, but we believe, based on the explanation of considering below in conjunction with accompanying drawing; Can understand the present invention better, the part that wherein identical parametric representation is identical.Response incoming call paging when calling out through only after setting up audio url between mobile communication equipment and the remote audio processor, setting up; The invention solves in remote audio processor; For example with the wireless headset of mobile communications device wireless link, receive the problem of the stand-by period in the process of the for example calling of dispatch call.
With reference now to Fig. 1,, what illustrate is according to the mobile communications device 100 of a kind of embodiment of the present invention and the block diagram of related network entity thereof.Mobile communications device 100 comprises communication transceiver 102, is used for communicating through the base station 104 of air interface 106 with communication network.Mobile communications device 100 also comprises local wireless transceiver 108, is used for and closes on the device of this mobile communications device, and for example remote audio processor 110, carries out radio communication.Remote audio processor can be, for example, wireless headset & microphone is conversed with the user that allows this mobile communications device and other people, and need not be taken this mobile communications device user's head.This mobile communications device and remote audio processor are through low-power, short-range wave point 112, and for example Bluetooth specification (www.bluetooth.org) communicates.
According to Bluetooth specification, communication is carried out on industry, science and medicine (ISM) frequency band of the not permission that is positioned at 2.4GHz.Transceiver utilizes frequency hopping to disturb and decline to reduce.Typical blue-tooth device has about 10 meters scope.Communication channel can support that total bandwidth is that the data (asynchronous) of 1Mb/sec are communicated by letter with audio frequency (synchronously).Synchronous voice channels is that utilization provides with the circuit switching that fixed intervals have reserved time slot.Synchronization links is called as SCO (towards synchronous connection) link.Asynchronous data channel utilizes packet switching to provide, and the poll access scheme is adopted in this packet switching.Asynchronous link is called as ACL (asynchronous no connection) link.Data-voice the SCO that has also defined a kind of combination divides into groups.This can provide the data of voice and the 64kb/sec of 64kb/sec in each direction.
In mobile communications device 100, local wireless transceiver can slave controller 114 or BBP 116 receive voice datas, this BBP 116 operationally is coupled to communication transceiver 102.Except that other tasks, BBP is also modulated signal and is sent signal through communication transceiver, and from cellular communication transceiver receiving demodulation signal.For example, can in the microphone that is connected to local audio processor 120 118, receive the wave audio signal.Generally when mobile communications device began to call out, local audio processor was signal digitalized with wave audio, and was provided to BBP to this digital audio and video signals to be used for transmission.Similar, BBP is provided to audio process to the digital audio and video signals that receives to play through loud speaker 122.When the headphone of outside or remote audio processor are not used, just use local audio processor.Usually, loud speaker 122 is parts of earphone and microphone is the part of microphone.The operation of each element of controller monitoring or subsystem comprises BBP, communication transceiver, local wireless transceiver and local audio processor.Controller is operated according to control or the instruction code and the various parameter that are stored in collective's memory (collective memory) 124, and collective's memory 124 can comprise RAM, ROM and semipermanent store, for example flash memory.In addition, controller helps user interface 126, and this user interface can comprise graphical display part 128, button and keyboard portion 130, audio-frequency unit 132 and vibrations or touch part 134.
In operation, remote audio processor is at first got in touch with mobile communications device.Between them, keep asynchronous link.In case after they linked, they just placed low power state to separately transceiver, and periodically power on to shake hands and determine whether need set up synchronization links with execution, for example when calling out.During calling out, remote audio processor has loud speaker 136 and microphone 138, and they are used for substituting the part that is connected to local audio processor.For fear of the problem of blocking a part of incoming call, mobile communications device will just be made response to the calling dispatch call page when only the link between mobile communications device and remote audio processor will reach total power, synchronous mode if having time.Accomplish these the whole bag of tricks is arranged.For example, mobile communications device can be waited for simply after synchronization links is set up.Another kind method is that response calling dispatch call page is postponed the selected one specific delays period; Even receive the calling dispatch call page at the beginning initial stage in the low-power stage of asynchronous link with assurance; Can, synchronization links not set up this calling dispatch call before setting up yet; Even mobile communications device responded to the calling dispatch call page before synchronization links is asked, also can utilize this response and set up the benefit that the inherent delay time between the time of calling out is brought between mobile communications device and the communication system.
Referring now to Fig. 2, what illustrate is the time-event table 200 that is used for reducing in the process that remote audio processor receives the for example calling of dispatch call the processing of obvious stand-by period according to a kind of embodiment of the present invention.Line 202 expression asynchronous link behaviors, the every link interval 204 of the simple handshake exchange of wherein between mobile communications device and remote audio processor, carrying out takes place once.Line 203 expression synchronization links behaviors.Link interval comprises active stage 206 and craticular stage 208.Active stage is mainly used in shakes hands, and can be referred to as to realize the phase (sniffperiod).Link is in most link interval inertia all, and local wireless transceiver and audio process are in low power state during during this period of time just.When the processing that does not have other will be carried out, two devices woke up during active stage simply to shake hands.When receiving calling, for example in the time 210, and link is in inertia, and local wireless transceiver must be waited for up to next active stage, thereby synchronization links is set up in request in the times 212.Subsequently, synchronization links was set up in the time 214, shown in the synchronization links line of locating to raise in this time.In case synchronization links is established, mobile communications device is in times 216 response incoming call paging, and incoming call was simultaneously set up or connected in the time 218.Because synchronization links was set up in the time 218, therefore do not lose any voice data of calling dispatch call, the user of remote audio processor will hear whole calling dispatch calls simultaneously.Those skilled in the art can know that this asynchronous link can convert synchronization links to, and perhaps they can keep independent mutually in same wireless carrier.Adopted blue tooth interface in an embodiment, asynchronous and synchronization links will be kept respectively.In addition, those skilled in the art can be known, before synchronization links is established, can take place a plurality of active stages 206.
Fig. 3 shows the replaceable time-event table 300 that is used for reducing in the process that remote audio processor receives the for example calling of dispatch call the processing of obvious stand-by period according to a kind of embodiment of the present invention.When the time 210 received the incoming call paging, mobile communications device waited for a period of time 302 before the time 216 of this paging of response.After the response incoming call paging, communication system needs minimum time section 304 to be connected to mobile communications device to calling.Shown in accompanying drawing 2, to calling out when being connected in the times 218, mobile communications device if having time in the times 212 request set up synchronization links 212, and synchronization links set up in the times 214, early than at times 218 call establishment.Therefore, when the time 210 received the incoming call paging, mobile communications device can be waited until the time 216; This time 216 is by chosen in advance; Considering connection delay time 304, thereby guarantee before call through, to set up synchronization links, perhaps wait until the operating lag phase; This operating lag phase can be the selected set time section except that connection delay time 304, thereby guarantees to set up synchronization links prior to call through.
In one embodiment of the invention, can use the combination of the processing shown in Fig. 2 and 3.Mobile communications device can start the processing of Fig. 3, if later but in link interval, should handle beginning ground, then synchronization links will be established before finishing period of delay 302 basically.Therefore, wait for until period of delays 302 with its continuation and to finish that mobile communications device can be before stopping period of delay, synchronization links responds the incoming call paging after being established simply.
According to another embodiment of the invention, mobile communications device 100 is avoided the audio loss of incoming call.Mobile communications device is at first through the data link of local wireless transceiver 108 foundation with remote audio processor 110.For preserving electric power, this data link is restricted to basically periodically shakes hands to confirm that the two continues to exist in wireless range each other.Packet switching capable of using of this data link and poll access scheme are to keep this link.In case communication transceiver 102 receives the incoming call paging, mobile communications device must wait for that the interval 206 of shaking hands is to ask between local wireless transceiver 108 and remote audio processor 110, setting up voice link.This voice link uses the circuit switching that has reserved time slot with fixed intervals.For guaranteeing that all speech datas that communication transceiver 102 receives can be relayed to remote audio processor 110, communication transceiver delayed response incoming call paging 210 is after the voice link between remote audio processor and local wireless transceiver 214 is established and during call establishment 218.
Referring now to Fig. 4, show the method flow diagram 400 that is used for receiving the process obvious stand-by period of minimizing of calling in remote audio processor according to a kind of form of implementation of the present invention.In beginning 402, mobile communications device powers on, and communicates with the base station of communication system, prepares receiving communication signal simultaneously.When beginning, method between mobile communications device and remote audio processor, sets up asynchronous link 404 through Local wireless network.In case set up, this asynchronous link just can remain on low power state.When the low-power link began, mobile communications device received calling incoming call paging 406 from communication system subsequently.Usually mobile communications device can respond to this paging immediately, calls out because in dispatching communication, need to set up rapidly.But,, before response, begin period of delay 408 according to the present invention.When began this period of delay, mobile communications device sought to set up the synchronization links with remote audio processor, and circulation starts from mobile communications device and confirms whether this synchronization link sets up 410.If synchronization link is not set up as yet, next mobile communications device confirms whether finish 412 period of delay.If do not finish period of delay, method continues circulation and finishes up to synchronization links foundation or period of delay, then mobile communications device response incoming call paging 414, and this calling is connected to mobile communications device 416 subsequently, and method finishes 418.Those skilled in the art can be known, although the present invention is with the obvious advantage for the calling dispatch call, other type of calls for example interconnect call also can be handled with same form of the present invention.Although it is so urgent that response interconnect is called out usually and called out unlike response scheduling, in the time of when working in low power state in, the present invention can be used to increase the time between the phase of shaking hands of asynchronous link, thereby allows the more electric power of saving.
Therefore, the invention provides a kind of method, be used for reducing the obvious stand-by period that the call chain that mobile communications device is received is connected to the process of remote audio processor.This method starts between remote audio processor and mobile communications device, setting up asynchronous link.In case mobile communications device receives the incoming call paging from wireless communication system, mobile communications device just begins to start the synchronization links between remote audio processor and the mobile communications device.Synchronization links has the synchronization links of foundation needed minimum settling time.Mobile communications device responds the incoming call paging sometime, so that set up synchronization links before between mobile communications device and wireless communication system, setting up incoming call.An embodiment of this method comprises, in case set up synchronization links, just after setting up synchronization links, responds the incoming call paging.An optional execution mode responds the incoming call paging after being included in a time of delay.Can select this time of delay with guarantee asynchronous link realize the phase after set up incoming call, asynchronous link realize the phase during, initiate synchronization links.If synchronization links was set up before stopping time of delay, then this method can be before stopping time of delay, synchronization links begins to respond the incoming call paging after setting up.Asynchronous and synchronization links can be set up through blue tooth interface.In addition, this method also comprises through user interface user's alarm to mobile communications device after synchronization links is set up has incoming call.
The present invention further provides mobile communications device, comprises local wireless transceiver, communication transceiver and the controller that operationally links to local wireless transceiver and communication transceiver.Local wireless transceiver is worked under asynchronous link pattern and synchronization links pattern, is used for communicating with remote audio processor.Communication transceiver and communication base station communicate.Local wireless transceiver and remote audio processor are set up asynchronous link, in case and communication transceiver receive the incoming call paging, communication transceiver just responds this incoming call paging when setting up the synchronization links pattern prior to call establishment.
The present invention further provides a kind of method, is used to avoid the audio loss between the mobile communications device and remote audio processor when call through.Method starts between the local wireless transceiver of remote audio processor and mobile communications device, setting up the data link.Certain time after setting up this data link, mobile communications device receives the incoming call paging at the communication transceiver place of mobile communications device.Receive after this incoming call paging, mobile communications device begins to initiate the voice link between remote audio processor and the local wireless transceiver, and this will cause setting up voice link.Only after setting up voice link and during call establishment, mobile communications device begins to respond the incoming call paging.Set up data links and can be included in most of link interval and keep local wireless transceiver to be in low power state, and shake hands in shake hands phase and remote audio processor of the periodicity of link interval.In one embodiment, response incoming call paging can be carried out before initiating voice link.In another embodiment, carry out after the period of delay that response incoming call paging can begin after receiving the incoming call paging.In a kind of optional execution mode, response incoming call paging can be carried out after setting up voice link.In the optional execution mode of another kind, response incoming call paging can take place in the two voice link or period of delay to carry out after early that setting up.
Although the preferred embodiments of the present invention are illustrated and describe, clear what can know is that the present invention is not limited to this.To those skilled in the art, can produce many modifications, variation, change, substitute and equivalent and do not depart from the spirit and scope of the present invention of liking enclosed in claims to be limited.
